Title: Image signal coding decoding device and its method
Inventor: TAKAMURA MASAYUKI
IPC: H04N19/50
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To provide the coding and decoding device and its method in which a coding efficiency is improved to the same degree as that of a conventional image coding system and an existing image coding and decoding device is used without any modification. SOLUTION: An input image signal I is given to a mean image generator 202, where a mean value for each block is calculated and the mean value is quantized by a quantization/inverse quantization device 203. This processing is made equivalent to the processing of a DC signal quantization device in an image coder 208. Then a smoothing image generator 204 smoothes a mean value image D while storing a mean value in a block. Since the mean value is stored therein, an in-block means value of a decoded image is kept unchanged. A subtractor 205 generates a difference between the smoothed image S and the input image I and an adder 206 adds the mean value image D to the difference. Then a clipping device 207 corrects the sum to be a proper value taken by the image signal. The signal obtained in this way is coded by the general image coder 208 and the code is outputted to an output terminal 209.

Abstract: PURPOSE:To reduce the number of errors produced at an automatic recognition operation and to reduce a standstill time of an apparatus by installing the following: a second-time recognition instruction means to execute a second-time recognition operation when an error is produced at the automatic recognition operation and a secondtime recognition repetition means. CONSTITUTION:When a recognition instruction signal is output to a recognition part 11 from a control part 12' through a signal line 13, a first target 3 is recognized. When it is not recognized at this time, an automatic recognition operation is repeated and the maximum prescribed number of operations are repeated. When this recognition operation is completed,a data 15 of a discrepancy amount used to correct a bonding position is output to the control part 12'; when the target is not recognized, this is first regarded as a recognition error and an apparatus is stopped. Also regarding a second target 4, the recognition part 11 executes the same treatment as for the first target 3 by a recognition instruction signal from the control part 12'. When the automatic recognition operation of the first and second targets 3, 4 is completed, a distance L of an arbitrary IC is compared with a distance set by a teaching operation; it is judged whether a check is OK and it is decided whether a bonding operation is to be executed or not.
Patent JP-H0377084-A (JP)
Title: Direction finder
Inventor: ONO TOSHIKI
IPC: G01S3/22
Filed: 1989-08-19
Abstract: PURPOSE:To make sure bearing detection in spite of the interference of other rader signals by adopting the constitution to change over the directional antenna element only at the point of the time when both conditions of the input pulse number and the elapsed time after the changing over of the directional antenna element are satisfied. CONSTITUTION:A logical circuit 12 outputs the AND signal of the control signals from a counter 8 and a timer 9 to an antenna changeover control circuit 10. Since the conditions for changing over the directional antenna element 3 are the AND of the input pulse number and the elapsed time after the changeover of the antenna element 3, the pulse repeating intervals of the radar to the direction-found is previously set in a timer 9. The antenna element 3 is not changed over by the mere input of the pulse signal of the other radar regardless of the prescribed number (n) of the pulses set in a counter 8. The antenna element 3 is changed over only after the pulse signal of the radar to be direction-found is inputted. The pulse signals of the direction finding radar are, therefore, received by the antenna element 3 over the entire circumference in spite of the interference of the pulse signals of the other radar. The bearing direction is thus possible.
